Abstract
A carbon monoxide sensor includes a housing providing an analyte inlet. Multiple electrodes are arranged in the housing and include a sensing electrode in communication with the analyte inlet. The sensing electrode includes a catalytic material niobium that is configured to oxidize carbon monoxide. Output elements are connected to the electrodes and are configured to provide a carbon monoxide signal in response to an analyte reacting with the sensing electrode.
